Please add the FreeBSD usage instructions #157

Closed yurivict closed 6 years ago

You should include the FreeBSD usage section: It is recommended that DNS requests are cached using nscd(8).

Enable nscd daemon with the command:

# sysrc nscd_enable="YES""

Start nscd daemon with the command:

# service nscd start

Enable nscd DNS cache by changing the "hosts" line in /etc/nsswitch.conf to: 'hosts: cache files dns'

Thanks @yurivict.

Can somebody on FreeBSD confirm this for me? A pull request would be great :-)

StevenBlack commented 8 years ago

I still need someone to try this n FreeBSD.

Guymer commented 7 years ago

Hi, I just tried this on my FreeBSD 11.1 box and it appears to work. I manually added the line nscd_enable="YES" to my /etc/rc.conf file rather than use the sysrc utility. That is just personal preference I think. My only comment on the whole method is that using nscd at all is optional. It will improve performance by caching the results of /etc/hosts but I think this is going to be of marginal benefit for my usage scenario.

Thank you for the input, Thomas @Guymer!

gfyoung commented 6 years ago

So is there really anything that needs to be added for FreeBSD? Sounds like these instructions weren't actually needed perhaps (can't confirm personally unfortunately)?

Guymer commented 6 years ago

I think a comment in the Reloading Hosts File section about enabling nscd and using nscd.conf on FreeBSD would be beneficial. The only difference between what I did and what @yurivict did was exactly how we each enabled nscd in rc.conf. @yurivict's way is safer for new FreeBSD users.

gfyoung commented 6 years ago

@Guymer : So what command would they use to clear the DNS cache after they have enabled nscd (didn't realize it wasn't enabled by default)? Something along the lines of nscd --invalidate=????

Guymer commented 6 years ago

@gfyoung : You can either restart the machine or run service nscd restart (as root) to restart the nscd service.

gfyoung commented 6 years ago

@Guymer : Gotcha. Just to double check:

The commands for enabling ncsd from @yurivict require root as well?
What is the full path to the nscd daemon? (e.g. /etc/inid.d/nscd) ?

Guymer commented 6 years ago

@gfyoung :

yes, the commands to enable ncsd from @yurivict require root; and
the full path to the nscd service script is /etc/rc.d/nscd and the full path to the nscd binary is /usr/sbin/nscd (though this really should not be relevant).

gfyoung commented 6 years ago

(though this really should not be relevant).

@Guymer : If you look at our code, we already have a section of logic for nscd. Hence, I wanted to double check that we could just incorporate it into that section instead of writing custom logic for FreeBSD.

Thanks everybody!
